Description

[Technical field]

[0001] Aspects of the present disclosure relate to improved golf club heads or portions thereof configured for tuning and customizing the golf club head, and more particularly, to modular putters. [Background technology]

[0002] The rules for the game of golf allow a player to carry 14 clubs that form a set. Typically, a player fills his set with various types and models of clubs to provide himself with maximum options for the variety of situations the player may encounter on the golf course. The most common groups of clubs are woods, hybrids, irons, wedges, and putters. The various designs of the club groups help the player launch the ball at different angles, heights, speeds, and distances. Some players purchase all 14 clubs in a single combination set, while others purchase the clubs bundled together by groupings, or even each club individually.

[0003] The putter tends to be the most unique club compared to the rest of a player's set. While the primary purpose of woods, hybrids, irons, and wedges is to launch the ball into the air, the putter is designed to roll the ball along the ground, especially on the putting green. Although the putter is typically used to move the ball the shortest distance, it is often the club a player uses most during a round. Players tend to need to make at least one putt on every hole, while on each individual hole they may not need to hit the specific distance or shape of the shot that the other clubs recommend.

[0004] Putters in the art come in a variety of shapes and sizes, with the best players in the world using a variety of putter types. Ultimately, the putter design must fit the player to provide the most consistent roll of the golf ball as the player swings the putter. Certain designs promote greater or lesser loft when swinging the putter. Other designs provide a higher level of moment of inertia (MOI) when the putter is not struck in front of the center of mass. Additionally, some designs promote a front-to-back swing, while others promote swinging the putter along an arc. For some players, the most important feature of a putter design is how it fits their personal swing style or visual preferences to encourage more confidence when putting.

[0005] With a typical conventional putter, a player is limited to the shape, weight, and appearance of the particular putter that the player selects. However, after an intense round of golf or upon swing modification, the player may find that a particular design no longer optimizes his / her game. To remedy this situation, the player may purchase a brand new putter or form a family of putters to rotate between. Purchasing multiple putters can be expensive, and maintaining a family of putters can take up significant space due to the size of the shafts and grips attached to the putters. Stores and club fitters face similar inventory problems with putters. To offer a full range of putters covering the numerous combinations of sizes, shapes, and weights, stores and club fitters must reserve significant space for inventory or limit their offerings. With limited offerings, stores and club fitters may not be able to offer for testing the exact characteristics that a customer may request.

[0006] Other existing putters have attempted to remedy these problems by providing interchangeable weights or removable sections. Existing systems with interchangeable weights allow players to optimize their putter in terms of total weight, but this can result in undesirable limitations in controlling the MOI or how the face moves during a swing. The interchangeable weights of existing systems are designed to fit in the same locations along the putter, so swapping different weights for one another changes the balance point and MOI of the putter. For example, a blade-style putter with two 5g weights in the center of the sole will have a different balance point and MOI compared to the same blade-style putter with two 25g weights in the center of the sole.

[0007] Additionally, some existing putters include multiple interchangeable components that allow for configurable head construction. However, such systems tend to lack a stable configuration for an assembled putter. Thus, over time and with impact, the separate pieces of these systems tend to loosen from one another. This can cause undesirable vibrations in these systems, resulting in inconsistent responses when the systems are in use.

[0008] Therefore, there is a need for an adjustable golf club head that allows a player to adjust the design and other features of the club head while maintaining a stable, properly weighted head. Summary of the Invention

[0009] The disclosed technology addresses these concerns, as well as other needs that will become apparent from the following description taken in conjunction with the drawings. Briefly, aspects of the disclosed technology relate to improved golf club heads that can be tailored with interchangeable pieces.

[0010] The disclosed technology can provide a putter-type golf club head including at least a first body, a second body, and a fastener. The first body can include a striking face, a first top surface, a first bottom surface, a first heel, a first toe, a first back wall opposite the striking face, and a hosel. The first body can be further defined by at least one first aperture extending from the bottom surface through the first body. The second body can be removably attached to the first body. As an example, the second body can be partially seated on the first body and / or a portion of the second body can be inserted into a portion of the first body. The second body can include a front surface, a second top surface, a second bottom surface, a second heel, a second toe, and a second rear surface opposite the front surface, the second body defining at least one second aperture extending into the second body, the front surface extending upwardly at an angle relative to an axis passing through the at least one second aperture. A fastener can be configured to extend through the at least one first aperture into the at least one second aperture for attaching the first body to the second body.

[0011] Another aspect of the invention can include a putter head that can include a first body, a second body, and a fastener.

The second body can be removably attachable to the first body. As an example, the second body can be partially in contact with the first body and / or a portion of the second body can be inserted into a portion of the first body. The second body can include a second sole, an upper surface of the second sole, a second heel, a second toe, a front surface, and at least one attachment interface formed on the second sole, the at least one attachment interface being configured to be attached to at least a portion of the upper surface of the first sole. The fastener can be configured to attach the first body to the second body. As one example, the fastener can create at least one force on the first body and the second body such that the first body and the second body join. As another example, the fastener can connect the first body and the second body.

[0012] Another aspect of the disclosed technology provides a putter head including a first body, a second body, a neck, and a fastener. The first body can include a striking face and a rear face, the rear face defining a channel. The neck can extend from an upper surface of the striking portion. The second body can be removably attached to the first body. The second body can include a second sole portion, an upper surface of the second sole portion, and a front portion attached to the second sole portion and defining at least one recess, the front portion can contact the channel, and the at least one recess in the front portion is configured to be aligned with the at least one aperture in the first sole. The fastener can extend through the at least one aperture and into the at least one recess to attach the first body to the second body.

[0013] A further aspect of the disclosed technology provides a method for customizing a putter head, the method may include aligning a first body with a second body; at least partially inserting the second body into a channel defined by the first body, wherein at least a portion of a front surface of the second body is configured to contact at least a portion of a rear surface of the first body and wherein the rear surface of the first body extends upwardly at an angle relative to an axis extending through an aperture defined by a bottom surface of the second body; and fastening the first body to the second body with fasteners, wherein the fasteners may extend through the first body and into the second body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] The disclosed technology includes modular golf club heads that can include removable elements that can adjust golf club head characteristics including weight and shape. The disclosed technology can include various interchangeable pieces that can be added to or removed from the modular golf club heads. The modular golf club heads can provide design flexibility and variety compared to counterparts in the art. As an example, the golf club head can be for a putter type golf club. The putter type golf club head can have a short second body part that is removably attached to a first body part with two 20g weight screws to form a heavy blade design. However, the 20g weight screws and the second body part can be removed and a different longer second body part can be attached to the first body with 5g weight screws to form a lighter mallet design putter. As will become apparent throughout this disclosure, the modular golf club heads can be easily configured to be adjustable and can include several variations of configurations that can each promote different swing and visual characteristics of the golf club. Additionally, the modular golf club heads can include features that increase the stability of the golf club head in an assembled configuration compared to existing technology. Additionally, modular golf club heads can be more efficient than those in the art by utilizing weighted fasteners to allow for easy tuning of the golf club head both in terms of changing weight and changing the placement of interchangeable pieces.

[0025] Moreover, in describing various aspects of the disclosed technology, terminology is used for the sake of clarity, and each term is intended to be accorded its broadest meaning as understood by one of ordinary skill in the art and to encompass all technical equivalents that operate in a similar manner to accomplish a similar purpose.

[0026] Various apparatus and methods for providing and using a multi-piece golf club have been disclosed, examples of which will now be described with reference to the accompanying drawings. FIG. 1A is an exploded view of a golf club head 100 in accordance with the disclosed technology, and FIG. 1B is an assembled view of the golf club head 100. As can be seen in FIG. 1A, an advantage of the present system and method is that the golf club head 100 can be easily assembled and disassembled to modify the weight distribution and performance of the golf club head 100. The golf club head 100 can have four main components, although other examples can have more or fewer parts (e.g., 1, 2, 3, 4, 5, etc.). The four main components can include a first body 105, a second body 115, and one or more fasteners 190. The first body 105, the second body 115 and the one or more fasteners 190 can be made from the same material (e.g., steel, aluminum, brass, copper, bronze titanium, carbon, zinc, etc.), or the first body can be made from a first material (e.g., steel) and the second body can be made from a second material (e.g., aluminum).

[0027] The golf club head 100 can be a putter as shown in FIG. 1A, however, it will be understood that the golf club head 100 is not so limited and can be an iron, wedge, hybrid, or wood type golf club head. As shown in FIG. 1B, the first body 105, the second body 115, and the one or more fasteners 190, when assembled, can form a mallet type putter head. However, one feature of the disclosed technology is that the golf club head 100 includes a modular design with the ability to switch out any one or more of the components of the golf club head 100 such that when assembled, the combined parts form a golf club head 100 having various characteristics. As an example, with reference to FIGS. 4A-4C, any one of the components shown can be replaced with another equivalent component. Similarly, with reference to FIGS. 5A-5C, any one of the components shown can be replaced with another equivalent component. Thus, between the six pieces shown in FIGS. 4A-4C and 5A-5C, nine different configurations can be assembled. In this manner, the multi-piece golf club head 100 can help reduce the cost, space, and availability associated with owning different styles of golf club heads.

[0028] 1A, the golf club head 100 may include a first body 105, a second body 115, and one or more fasteners 190. The first body 105 may form a front portion of the golf club head 100, and the second body 115 may form a rear portion of the golf club head 100. As described in more detail herein, when assembled, the first body 105 and the second body 115 may apply normal and shear forces to one another to secure the first body 105 and the second body 115 to one another. In this manner, the first body 105 and the second body 115 may form a stable golf club head 100.

[0029] The first body 105 may include a striking face 110, a first heel end 145, a first toe end 140, a ledge 127 defining a first upper surface of the first body 105, a hosel 125, a first sole 150, and at least one aperture 170, recess, and channel 160 extending through the first sole 150. For illustrative purposes, the golf club head 100 of FIG. 1 is shown as a putter-type golf club head. However, it will be understood that iron, wedge, hybrid, or wood-type golf club heads are suitable for such a configuration.

[0030] The channel 160 can be formed on the opposite side of the striking face 110 such that the channel 160 forms at least three sides. A first side of the channel 160 can be defined by the bottom surface of the ledge 127, a second side of the channel 160 can be defined by a rear wall 310 substantially opposite the striking face 110, and a third side of the channel 160 can be defined by a top surface 350 of the first sole 150, which can extend from the channel 160 to form a shelf. The channel 160 can extend from the first toe end 140 to the first heel end 145 and have an opening at each end. As will become apparent throughout this disclosure, the channel 160 can be configured to receive a portion of the second body 115. In this manner, the channel 160 can help hold the second body 115 in place when the golf club head 100 is in an assembled configuration.

[0031] The first sole 150 can be substantially flat, or the first sole 150 can be arcuate or otherwise curved from the first toe end 140 to the first heel end 145 such that when the bottom surface of the first sole 150 is placed on a flat surface, at least a portion of the bottom surface of the first sole 150 does not contact the flat surface. The first sole 150 can define a recess 180 between the first toe end 140 and the first heel end 145. The recess 180 can extend from the rear end of the first body 105 toward the striking face 110. As will become apparent throughout this disclosure, the recess 180 can be configured to receive at least a portion of the second body 115. Although only a single recess 180 is shown, in some examples of the disclosed technology, multiple recesses can extend from the rear end of the first body 105 toward the striking face 110. The rear wall 310 defining the second side of the channel 160 can be parallel to a plane along the striking surface 110, although in other examples, the rear wall 310 can be formed at a tangential angle or otherwise non-parallel to the plane along the striking surface 110 to create a slanted appearance. The rear wall 310 defining the second side of the channel 160 can be perpendicular to the first and third sides of the channel 160, although in other examples, the second side can form an acute angle with the first side defined by the bottom surface of the ledge 127 and an obtuse angle with the third side defined by the top surface 350 of the first sole 150.

[0032] As shown in FIG. 2, the at least one aperture 170 can extend through the first sole 150 at an angle A1 that is neither perpendicular nor parallel to the rear wall 310 that defines the second side of the channel 160. That is, the axis AX1 extending through the at least one aperture 170 can be non-parallel to the plane P1 defined by the rear wall 310. The angle A1 can be, for example, approximately 10 degrees. In other examples, the angle A1 can be approximately 2 degrees, 5 degrees, 15 degrees, 20 degrees, 30 degrees, 45 degrees, 60 degrees, 75 degrees, or another suitable angle generally between 1 and 89 degrees. In some examples, the angle A1 is between 2 and 45 degrees. As will be appreciated, the relationship between the angle A1 of the rear wall 310 and the aperture 170 can facilitate the first body 105, the second body 115, and the fastener 190 applying a multi-directional force to each other, thereby securing the first body to the second body 115. As an example, the second body 115 can apply both normal and shear forces to the first body 105 when the second body 115 is attached to the first body 105 via the fasteners 190. As another example, the second body 115 can apply forces to the first body 105 in a direction parallel to an axis AX1 extending through the apertures 170 and in a direction perpendicular to the axis AX1 extending through the apertures 170. The at least one aperture 170 can include a lip 171 extending radially inward from a circumference of the at least one aperture 170. The lip 171 can be sized to prevent a portion of the fasteners 190 from extending over at least the aperture 170.

[0033] 1A , the second body 115 of the golf club head 100 can include a front surface 111, a second top surface 355, a second sole 155, a second heel 146, a second toe 141, a second rear surface 360 ​​opposite the front surface, at least one mounting interface 158, a protrusion 185, and at least one second aperture 175 extending into the second body 115. As will be appreciated, the second sole 155 can be substantially flat, or the second sole 155 can be arcuate or otherwise curved from the second toe 141 to the second heel 146 such that when the bottom surface of the second sole 155 is placed on a flat surface, at least a portion of the bottom surface of the second sole 155 does not contact the flat surface. The second sole 155 can include a protrusion 185 extending toward the front surface 111 between the second toe 141 and the second heel 146. Although only a single projection 185 is shown, multiple projections can extend toward the front surface 111. The bottom surface of the second sole 155 can have at least one mounting interface 158 recessed therein, and the at least one mounting interface 158 can be configured to receive at least a portion of the top surface 350 of the first sole 150. The at least one aperture 175 extending into the second body 115 can extend at an angle A1 that is neither perpendicular nor parallel to the plane P1 defined by the front surface 111. In other words, the axis AX1 of the at least one aperture 175 extending into the second body 115 can be non-parallel to the plane P1 defined by the front surface 111. The at least one aperture can include a thread 176 that extends helically and radially inwardly along the circumference of the at least one aperture 175. As shown, the front surface 111 can include at least one cavity 135. The second body 115 may further include a pair of wings 156 extending outwardly from the second rear face 360 ​​.

[0034] The one or more fasteners 190 can be weighted screws (e.g., screws having a Phillips head, flat head, Torx head, etc.), bolts, clips, and / or magnets. The one or more fasteners 190 can be inserted at least partially through the aperture 170 of the first body 105 and at least partially into the aperture 175 of the second body 115. As can be appreciated by one of ordinary skill in the art, the extension of the at least one fastener 190 can apply shear and normal forces between the first body 105 and the second body 115 due to the orientation of the apertures 170, 175 and the front face 111 and rear wall 310 described herein. The fastener 190 can extend the entire length of the apertures 170, 175, or the fastener can extend partially into the apertures 170, 175. The fastener 190 can be substantially cylindrical in shape. The diameter of the fastener 190 may be approximately 0.5 inches, 1 inch, 1.5 inches, 2 inches, or another suitable length, typically between 0.2 and 3.5 inches. The height of the fastener 190 may be approximately 0.2 inches, 0.5 inches, 1 inch, 1.5 inches, 2 inches, or another suitable length, typically between 0.1 and 3 inches. The fastener 190 may include a thread 192 that extends helically around at least a portion of the circumference of the fastener 190 and extends radially outward. The fastener 190 may include a ledge 195 that extends radially outward from the fastener 190 and is configured to contact the lip 171 of the first body 105. The diameter of the ledge 195 may be approximately 0.5 inches, 1 inch, 1.5 inches, 2 inches, or another suitable length, typically between 0.25 and 3.5 inches. The fastener 190 may include a keyhole 196 configured to receive a screwdriver or other fastening device. The keyhole 196 can include a variety of shapes, for example, a cross, a star, a Torx receiver, etc.

[0035] The fasteners 190 can be selected in a variety of weights, typically between 2 and 50 grams, e.g., 5g, 10g, 15g, 20g, 30g, 40g, 45g. The fasteners 190 can be a continuous piece of material or can include hollow sections. The fasteners 190 can be made from a variety of materials (e.g., steel, aluminum, brass, copper, bronze titanium, carbon, zinc, etc.). Thus, two fasteners 190 of the same weight, e.g., 10g, can have different weight distributions and / or different sizes depending on the material and composition. As will be appreciated, different fastener weights, heights, and weight distributions can affect the balance point of the assembled golf club head 100 and thus affect the performance of the golf club head 100.

[0036] Although illustrated and described herein as golf club head 100 formed by first body 105 and second body 115, it will be understood that additional bodies may be attached to form golf club head 100. For example, in some instances, wing 156 may be removably attachable to second body 115. Similarly, second body 115 may be separated into a second toe 141 side portion and a second heel 146 side portion. Additionally, each additional body portion may define an aperture through which fastener 190 may extend.

[0037] FIG. 2 illustrates an assembled configuration of the exemplary golf club head of FIG. 1. The assembled golf club head 100 can have various parts connected to form a single continuous shape. The mounting interface 158 of the second body 115 can seat on the top surface 350 of the first sole 150 such that the bottom surface of the first sole 150 can be continuous with the bottom surface of the second sole 155. The aperture 170 of the first body 105 can be aligned with the aperture 175 of the second body 115 such that the fastener 190 can extend through the apertures 170, 175 and the surface of the shelf 195 of the fastener 190 can be continuous with the bottom surface of the first sole 150. In the assembled configuration, the protrusion 185 of the second sole 155 can extend flush into the recess 180 of the first sole 150. In the assembled configuration, the front surface 111 of the second body 115 can abut the rear wall 310 that forms the second side of the channel 160 of the first body 105. A portion of the top surface 355 of the second body 115 can at least partially abut a bottom surface of the ledge 127 of the first body 105.
